Authorities responded to a residence in the 100th block of East 5th Street for a stabbing around 11:55 a.m. on Sunday.

Police located Davis, of Duluth, at the residence and she was transported to St. Lukes Hospital, where she died of her injuries. Revello was found in the back bedroom of the residence and was arrested.

According to the criminal complaint, Revello and Davis began arguing over a bag of clothing. The complaint states that Revello admitted to investigators that she intended to kill Davis and did so because she "had to shut her up".

An autopsy revealed that Davis died of a single stab wound on her back that severed her pulmonary artery, with the knife continuing through Davis' lung and puncturing her aorta . The criminal complaint states that when authorities asked Revello why she did not aid the victim after she stabbed her, Revello stated that "that wasn't the point."

In the courtroom, the prosecuting attorney called the stabbing a "cold and calculated attack." She stated that the location of the single stab wound and removing the knife was intentional so Davis would bleed to death.

The knife used by Revello was located in the residence along with a tool to sharpen knives.

The judge set bail for Revello at $250,000. Her next court appearance is scheduled for June 26 at 1:30.
